E-mail addresses are an artificial way of directing messages to the right people, says Michael Genesereth, an associate professor of computer science at Stanford who works on SEAmail. “You want to send messages to people or roles, not to strings of characters,” he says. Semantic technologies are aimed at making just this sort of thing possible. The idea is to create programs that understand context, so that users can interact with the software more naturally. Technical details, such as the need to specify an e-mail address, get hidden inside the system, so that everyday users no longer have to pay attention to them.
In SEAmail, a user selects recipients for a message in much the way that she would set up a search query. The parameters can be as simple as a person’s name, or as complex as sets of logical requirements. But the system is limited by how much information it has about potential recipients. “To realize the full potential, we need to have rich data about the people who are sending messages to each other, their interests, and so forth,” Genesereth says. Within an organization, he says, there’s usually a lot of available data. The technical challenge is setting up an integrated version of the data that SEAmail can access easily. The data needed to fulfill the request for professors who graduated from Harvard, for example, would probably come from several databases, Genesereth says. His team is currently researching ways to pull together existing databases without affecting how they’re already being used.
These existing databases should be part of the Linking Open Data Movement, which aims to semantic interlink existing open data sets in order to build useful new applications and to support a Web of Data.
SuggestRSS is a service suggesting feeds based on your actual feeds. Just upload a OPMLexport of your current subscribed feeds and you are going to get nice new suggestions. I tried it out and think it is very useful.
Sergej Maslow and Sidney Redner, both researchers have found out that Google‘s Page Rank algorithm could be used to predict future nobel price winners based on interlinked scientific papers. Scientific papers are interlinked by references, just like websites are which means they can be ranked by googles page rank algorithm. Taking into account how important a paper is, it is possible to generate a list of wighted ranked scientific papers.
Theory of the Fermi Interaction by Feynman & Gell-Mann
Absence of Diffusion in . . . by Anderson
The Theory of Complex Spectra by Slater
Scaling Theory of Localization by Abrahams, Anderson, et al.
That’s an impressive list, not least because most of these authors are Nobel Prize winners. (Curiously the author of the top paper, Nicola Cabibbo, is not. That ought to be of interest to the Nobel committee who awarded Makoto Kobayashi and Toshihide Maskawa the 2008 Nobel Prize for physics for work that was heavily based on Cabibbo’s ideas.)
All of which suggests an idea. Mining the later entries in this list might be an good way of predicting future prize winners. So get your bets in before the bookies get wind of it.
Redner and Maslov conclude: “Google’s PageRank algorithm and its modifications hold great promise for quantifying the impact of scientific publications.”
Well that’s an interesting example on how interlinked data can be processed in order to predict meaningful information. In terms of Semantic WebLinking of Open Data should be provided by every new application on internet. This example illustrates how interlinking of library data increases the possibility to generate new information.
Dieser Artikel beschäftigt sich mit Anwendungen, die das Linking Open Data Konzept verwenden. Zuerst wird auf das Open Data Movement eingegangen und anschließend auf das W3C SWEO Linking Open Data Community Project. Es sind zahlreiche Anwendungen entstanden, die Linked Open Data verwenden und daraus einen Mehrwert für Benutzer erzielen. Eine dieser Anwendungen ist Freebase, die von der Firma Metaweb Technologies Inc. entwickelt wurde. Weitere Anwendungen sind aus dem MITSIMILE Project hervorgegangen und werden hier auch aufgelistet.
Internet of Services makes live of young parents easier
Once a baby is born the organization marathon is just starting for it’s parents: register the birth, register with the health insurance, apply for parents allowances and arrange a lot of other appointments. SAP Research is developing an internet platform aimed at helping youg parents. Automated Services will connect authorities and service providers with each other by the internet. This saves time and lakework in the future.
I have found an interesting video through the SAP Website covering the “Internet of Services issue”. Check out an watch it here:
ReadWriteWeb has published a great list of 10 interesting semantic apps at the end of 2007. Now in year 2009 some of them have matured. Check out Freebase which let’s you access a huge space of linked open datasets.
